In contrast, distributed AOP is a paradigm that allows distributed interception. It defines many new concepts like remote pointcuts, which are similar to traditional remote method calls, since execution is performed on a remote host. Thus, distributed AOP establishes a context where aspects can be deployed in a set of hosts.
Whenever users modify the database, we want to have a log of information regarding who is modifying the records. The traditional way to log is to call a log method just before modifying the database. With aspect-oriented programming, we can apply pointcut to the Modify Database method and have an advice that is called to log the required ...
